Convert a two-prong outlet into a three-prong outlet by turning off the power at the fuse box, removing and replacing the receptacle, grounding the connection, then restoring power and testing the circuit. As long as the metal outlet box holding the outlet is grounded, it doesn't need to be rewired.Know More
Place one prong of a circuit tester in the shorter slot of the two-prong receptacle and touch the other to the screw on the cover plate. If the tester lights up, the box is grounded. If it's not grounded, an electrician should rewire it or install a ground fault circuit interrupter.
Turn off power at the fuse box, then remove the two-prong receptacle and detach the two wires. Attach the black wire to the brass terminal on the three-prong outlet and the white wire to the silver terminal.
Obtain an 8-inch grounding wire and screw (available at hardware stores), and use the screw to connect one end of the wire to the back of the box. There's a threaded hole at the back for this purpose. Connect the other end of the ground wire to the green terminal on the three-prong outlet. Screw the new terminal back into the metal box.
Restore power and use the circuit tester the same way it was used in step one to be sure the circuit is working.
To convert a 220-volt outlet to a 110-volt outlet, either purchase an adapter or remove the existing receptacle from the outlet box. Either option allows a 110-volt appliance to plug into a previously 220-volt outlet.Full Answer >
A breaker may be bad if a circuit running from the breaker panel box has lost power. A process of elimination can determine if a faulty breaker is the problem. Test to see if the breaker has simply been tripped. Firmly move the switch on the breaker from the on position to the off position and then back again.Full Answer >
To rewire or repair a damaged three-prong extension cord, remove the damaged portion, and cut through the cord's outer jacket to expose the inner wires. Replace the damaged plug with a plug of the same style, voltage level and amp rating. Along with a new plug, necessary tools include a pair of wire strippers with a cutting tool, a utility knife, a Phillips head screwdriver and electrical tape.Full Answer >
To install, a GFCI outlet, turn off the power to the affected room at the circuit box, take out the existing outlet, identify and connect the line wires, followed by the load wires. Put the GFCI into the wall box, and put the wall plate over the outlet.Full Answer >
